Theme Name: Grotto
Description: Contemporary project space for grotesque figuration and abstract art.
Version: 1.0

/* ============================================================
   Grotto's structural principle: the homepage collection grid is
   a salon-hang — irregular sizes, small rotations, uneven gutters,
   the way 19th-century academy exhibitions actually hung work floor
   to ceiling — instead of the uniform card grids every prior theme
   in this project has used. Three new GPU techniques debut here:
   a marching-cubes isosurface (real mesh generation from a metaball
   scalar field, not raymarching, not InstancedMesh — the project's
   first polygon-generating GPU algorithm), a real-time liquify/melt
   vertex+UV displacement on framed artwork images, and a metaball
   goo cursor (2D screen-space distance-field blob union replacing
   the pointer sitewide). Palette: bruise purple-black, bilious
   acid green, raw flesh pink — deliberately uncomfortable, never
   used before. Typography: Hanken Grotesk (literally a "grotesque"
   type classification) + Archivo + Azeret Mono. The interaction
   model stays a normal scrollable site — the strangeness lives in
   surface and layout, not in how the page behaves.
